The Snyder Industries 4400 Gallon Cone Bottom Tank is a black polyethylene cone bottom tank built for full-drain bulk chemical storage and dosing, rated to a 1.5 specific gravity and standing 200 inches tall on a 90 x 90 inch footprint. Snyder molds this tank in Lincoln, Nebraska, and the cone discharge means the tank empties completely with no heel left sitting in the bottom - the reason cone bottom tanks are the standard for batching, mixing, and metered chemical feed where you cannot afford stagnant product.
Will it work for your application
At 4400 gallons this tank carries 36,696 lb of contents when full of water; at its 1.5 SG rating the maximum rated contents weight is 55,044 lb, so size the stand and slab to that loaded figure, not the empty shell. The cone shape requires elevation on a matching cone bottom stand - the discharge sits below the cone, not on the ground - so plan the support structure before delivery. The technical drawing on this page shows the molded fittings: a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for inspection and cleanout. Run the loaded weight and your duty cycle through the Tank Sizing Calculator, and see the Tank Sizing Guide if you are deciding between cone bottom and flat bottom geometry.
Chemical compatibility
This tank is rated to 1.5 specific gravity. The resin designation is not confirmed in our data, so confirm whether the construction is HDLPE or XLPE before committing it to chemical service. At the 1.5 SG rating, this tank is suited to Acetic Acid (60%, PP/PVC fittings on EPDM), Aluminum Sulfate (50%), Calcium Chloride (40%), DEF (32.5%, 316SS fittings / EPDM), Ferrous Sulfate (20%), Magnesium Chloride (30%), Sodium Carbonate (30%), and Urea Solution (50%, PP/PVC on EPDM). Most of these run PVC fittings with EPDM gaskets; match the fitting and gasket materials to the chemical. Ozonated Water (up to 10 PPM) runs PVC fittings on EPDM; we do not have a standing compatibility page for it, so confirm the ozone concentration and contact time with us before ordering.
Several heavier chemicals exceed what a 1.5 SG tank should hold and require you to step up to a 1.9 SG cone bottom tank instead; confirm the required 1.9 SG rating in the Chemical Compatibility Database before ordering so you don't commit this 1.5 SG shell to a chemical it isn't rated for. Among them are Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Several of those - Hydrochloric Acid, Hydrofluoric Acid, Hydrogen Peroxide, Phosphoric Acid, Sodium Hypochlorite, and Sulfuric Acid - need Viton gaskets, with fittings ranging from PVC to CPVC rather than standard EPDM pairings. Peracetic Acid is the exception that needs an Aflas gasket with 316SS fittings - do not default it to Viton. Always verify against the OEM chemical-resistance chart at the specific concentration and temperature of your process before ordering.
Specifying it correctly - the mistake to avoid
The single most common error on a cone bottom chemical tank is matching the tank to the chemical name but not to its specific gravity. This tank is built for 1.5 SG; putting a product that exceeds the 1.5 SG rating into it shortens wall life and voids the rating. Confirm your chemical's SG against the 1.5 limit first, then confirm the resin and the fitting and gasket materials above. For containment planning, see the Snyder Captor Plus 110% containment vs UL-142 / SPCC comparison; for the support structure, the cone bottom tank stand compatibility matrix; for monitoring, the tank level gauge selection guide; and for labeling, the bulk polyethylene tank label and signage compliance guide.
This tank ships LTL from Snyder's plant in Lincoln, NE, and freight is quoted live to your ZIP - get your number with the Freight Cost Estimator or call 866-418-1777. Because this is a large cone bottom unit requiring elevated support, confirm your stand and discharge plumbing before it leaves the dock.
